One of the best series I've ever enjoyed, on any network, was Guns, Germs & Steel on PBS. Jared Diamond's book turned into a documentary regarding native cultures and their doomed futures as Western power and greed arrived.
Though migration of peoples was a necessity driven by overpopulation, war, poverty and other common elements throughout time, the existence of conflict and conquest just as pervasive. The winners occupy. Losers have to leave. True in pre-contact era. True today.
Diamond's ability to weave history and simplify the power of Western weaponry — guns, germs and steel — makes for a fascinating watch. I wish we had this to watch when I was back in school.
